LED lighting cable calcs

Baldyhugh over 4 years ago

Hi all

when calculating cable size for an LED lighting circuit is there a multiplication factor to be applied like the 1.8 for the old fluorescent lighting? I’m aware of the high inrush currents of led fittings but what I understand of this it is of such short duration that it only affects the curve rating of the mcb selection. I have a couple of 150 disco Lowbays to fit in a warehouse and would appreciate some advice.

many thanks

Hi Hugh, on a recent job I had 11 of 100W led floods and 12 of 50W led floods, out of interest I temporarily put them all together on one switch and they started up fine on a B6 MCB. They are now on multiple circuits/switches.

Hope this helps! :)
